如何使用POI设置Blank excel单元格

I have a condition where in I need to check for the Delimiter in a string. If found then I need to set excel cell to blank. I have this code:

我有一个条件，我需要检查字符串中的分隔符。如果找到，那么我需要将excel单元格设置为空白。我有这个代码：

                row = sheet.createRow(newRow);
            for(String fieldValues: fieldList)
            {
                if(fieldValues.contains(","))
                {
                    XSSFCell cell = row.createCell(cellNo);
                    cell.setCellValue(Cell.CELL_TYPE_BLANK);
                    cellNo++;
                }
                else
                {
                    XSSFCell cell = row.createCell(cellNo);
                    cell.setCellValue(fieldValues);
                    cellNo++;
                }
            }

Cell.CELL_TYPE_BLANK is not setting up the Blank Cell even I tried with cell.setCellValue("") but again it doesn't set. Does it try to skip that cell if we want to set a Blank Cell? if not then can anyone let me know how I can do that.

即使我尝试使用cell.setCellValue（“”），Cell.CELL_TYPE_BLANK也没有设置空白单元格，但是它再次没有设置。如果我们想要设置空白单元格，它是否会尝试跳过该单元格？如果没有，那么任何人都可以告诉我如何做到这一点。

Appreciate your help!!

感谢你的帮助！！

#1

According to the Documentation and POI implementation I'd expect that

根据我希望的文档和POI实现

cell.setCellType(Cell.CELL_TYPE_BLANK);

should do the trick and is all you need.

应该做的就是你所需要的。

You are using setCellValue. Instead use this method : setCellStyle

您正在使用setCellValue。而是使用此方法：setCellStyle

row = sheet.createRow(newRow);
for(String fieldValues: fieldList)
{
  if(fieldValues.contains(","))
  {
    XSSFCell cell = row.createCell(cellNo);
    cell.setCellStyle(Cell.CELL_TYPE_BLANK);
    cellNo++;
  }
  else
  {
    XSSFCell cell = row.createCell(cellNo);
    cell.setCellValue(fieldValues);
    cellNo++;
  }
}
